Q355NHB steel plate is atmospheric corrosion-resistant steel plate, also known as weather-resistant steel plate. It is a low alloy steel series between general steel and stainless steel. Weather-resistant steel is made of ordinary carbon steel with a few corrosion-resistant elements such as copper and nickel. SA514 Grade P high strength construction steel coil, Q355NHB steel sheet is featured by good toughness, plastic extension, forming, welding and cutting, abrasion, high temperature, fatigue resistance, etc.
